MEANS FOR TRANSMITTING ROTARY MOTION.

Specification of Letters Patent.

Patented Sept. 2, .1 913.

Application filed December 7, 1912. Serial No. 735,479.

To all whom it may concern Be it known that I, ADRIAN DENMAN Jonns, a subject of the King of Great Britain, residing at 39 Hartham road, Holloway, in the county of London, England, have invented new and useful Improved Means for Transmitting Rotary Motion, of which the following is a specification.

The object of this invention is to provide improved mechanism whereby a body can be rotated in either direction at will but that unintentional movement in the wrong direction shall be impossible. Such mechanism is especially applicable to winches and h like for by it a load can be readily hoisted and readily lowered but there will be no danger of the load running down. For the sake of simplicity therefore the invention will be described as applied to a winch but it is obvious that it may be applied to other apparatus.

The accompanying drawings show a winch constructed in accordance with this invention, Figure 1 being a front view and Figs. 2 and 3 sections on the lines 2-2 and 3-3 of Fig. 1.

a is the barrel mounted loose on an axle Z) carried by the casing c in which can turn a disk d having 011 it a crank pin 0 to which is pivoted one end of a plate f the other end of which is pivoted to a crank pin 9 on the flange of the barrel, the two pins being 180 apart. In the disk are cut a hole h and a slot i and opposite this slot is a hole 7' in the flange of the barrel.

is is a crank handle carrying a fulcrum pin Z which can be inserted into the axle Z) and a driving pin m. adapted to engage the holes h and 7'.

n is a guide roller for the hoisting rope 0.

The handle is shown in the position for unwinding. If the handle be rotated in an anti-clockwise direction, the pull of the rope will rotate the barrel as fast as it is allowed to do so by the handle.

To hoist the load, the handle is taken out and turned around so that the pin 1% asses through the slot i into the hole j so t rat it can drive both barrel and disk clockwise but should an attempt be made to rotate the pin in the wrong direction, or should the load attempt to run down, the plate f jams and the whole is rendered immovable by the friction. IV hen the winch is not being operated by the driving pin it cannot turn in either direction.

Care must be taken that the plate f shall be clear of the driving pin in either position and that the plate shall not come against the axle when it is rocked on either of the crank pins.

'lhough it is essential that there should be some friction between the disk and its hearing, it is not necessary to make the surfaces rough as with the surface machined in the ordinary way the friction is sullicient to cause the parts to jam even if a lubricant be employed.

hat I claim is 1. In appa 'atus for transmitting rotary motion the combination of a member rotatably mounted in a frictional bearing, a second member rotatably mounted co-axial with the first, two crank pins 180 apart one on each member, a plate pivoted to the two pins, means for rotating one of the members and means for securing the two members together.

2. In apparatus for transmitting rotary motion the COIlllOllltllllOll of a member rotatably mounted in a frictional bearing, a second member rotatably mounted co-axial with the first, two crank pins 180 apart one on each member, a plate pivoted to the two pins, means for rotating one of the members and a pin passing through a slot in one member and a hole in the other.

3. The combination with a rotatable member of a disk mounted in frictional bearings co-axial with the rotatable member, two crank pins 180 apart, one pin being on the rotatable member and the other on the disk, a plate pivoted to the two pins and means for actuating the rotatable member and disk.

I. The combination with a rotatable member of a disk mounted in frictional bearings hole in the plate and also to pass through co-axial with the rotatable member, tWo the slot in the plate and engage a hole in crank pins 180 apart one pin being on the the rotatable member.

rotatable member and the other on the disk, ADRIAN DENMAN JONES.
